That's not all. I noticed while I was testing this feature that Apple no longer restricts embedded fonts to non-special tags, as I describe on page 140 of my EPUB book. This is a really big deal, and means you can forget the ugly hacks previously required to get them to appear.

Liz Castro has simple instructions on her site to make ePubs work with embeddable fonts-and as a bonus, these ePubs also will work on the Nook!
